ADJUSTABLE OFFSET FOR RAILWAY SWITCHES AND SIGNALING APPARATUS.

Application filed October 19, 1915.

To all whom it may concern:

Be it known that I, BERT SHERWOOD, a citizen of the United States, residing at Jordan, in the county of Onondaga and State of New York, have invented certain appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustable connections for railway signal and switch apparatus and consists of a simple and efficient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of the invention. Fig. 2 is a sectional view, and Fig. 3 is a detail view of a part of the invention.

Reference now being had to the details of the drawings by letter, A designates a jaw having a forked end with apertures therein adapted to be attached to the arm of a crank, not shown. The shank portion of said jaw is threaded and engages threads formed in the interior of the elongated aperture in one end of the offset D, and a lock nut E is fitted to the end of the threaded part of the jaw. Said offset is provided with a second opening .N upon the opposite end thereof and about one end of which are serrations O. A screw H is mounted in said aperture N and is provided with jam nuts J and J, upon one end, and Q, designates a washer having serrations Q formed upon one end adapted to engage the serrations formed in the offset member about the aperture N. Said washer has oppositely Specification of Letters Patent.

disposed notches T therein adapted to engage the teeth S projecting from the face of the collar S which is integral with the screw. A coupling, designated by letter W, is interiorly threaded and is adapted to receive a rod X and also a threaded end of said screw.

By the provision of an offset made in accordance with my invention. it will be noted that a great deal of time and labor will be dispensed with in making offsets in jaws and cranks upon apparatus connected with signal and switch throwing means and, by the construction shown, provision is made for ready adjustment of the parts.

What I claim to be new is 1. An offset for switch and signal throwing apparatus comprising a plate having parallel apertures therein, one of which is interiorly threaded, a threaded rod engaging the threaded opening and having a forked end to which a crank arm is adapted to be fastened, a screw mounted loosely in the other opening and about which openings at the end thereof are serrations, jam nuts upon the screw, a serrated washer upon the screw, and means for holding the serrations upon the washer in engagement with the serrations upon said plate.

2. An offset for switch and signal throwing apparatus comprising a plate having parallel apertures therein, one of which is interiorly threaded, a threaded rod engaging the threaded opening and having a forked end to which a crank arm is adapted to be fastened, a screw mounted loosely in the other opening and about which openings at the end thereof are serrations, jam nuts upon the screw, a serrated washer upon the screw, said screw having a collar with integral teeth thereon and the washer being provided with notches for the engagement of said teeth upon the collar.

In testimony whereof I hereunto aflix my signature-in presence of two witnesses.
